gaussianBlurImage

Blurs an image. We convolve the image with a Gaussian operator of the
given radius and standard deviation (sigma). For reasonable results, the
radius should be larger than sigma. Use a radius of 0 and selects a
suitable radius for you.

Parameters

radius

float

The radius of the Gaussian, in pixels, not counting the center pixel.

sigma

float

The standard deviation of the Gaussian, in pixels.

channel

int

Provide any channel constant that is valid for your channel mode. To
apply to more than one channel, combine channeltype constants using
bitwise operators. Refer to this
list of channel constants.
